摘要
以成都市为例,据1981-2000年逐日日平均气温、日最高气温、日最低气温及大气能见度的统计表明:80年代以后成都市区呈现变暖的趋势,人体舒适度逐年变差,夏季变长,冬季变短.用主成份分析结果表明:第三产业生产总值、工业总产值城市房屋建筑竣工面积是影响成都市气温升高的主要因子,其次为道路铺装面积.这就为改善成都市生态环境,创建绿色城市提供科学依据.
This text takes Chengdu as an example. Statistics of atmosphere visibility, average temperature day by day, daily highest and lowest temperature of 1981-2000 shows that the climate of Chengdu is becoming warmer, summer longer and winter shorter. The main component analysis shows： total output value of the tertiary industry, completed floor space of the city and total output of industry are the main factors of temperature rising in summer in Chengdu, and paved area makes minor contribution. This result establishes the scientific basis in improving the ecological environment in Chengdu.
